Fuk yeah, they can... They're good people, though, too. In 2010 I ordered a gen-u-wine Armalite 16" midlength gas 5.56 barrel from them - to be for a birthday-present build. The barrel that came in was a 20" rifle gas barrel... I called them immediately, and explained that I got the wrong barrel shipped, and had 4 days to get this gun built. They told me not to worry about it, and they'd take care of it. They overnighted me the correct barrel, and and included the shipping tag for the return of the other barrel. They didn't even need the other barrel back first... "Just put it in the box that this next one comes in, same packaging and padding, tape it up and stick that label on it..." Fuk yeah!
They fuckin' rock, and that solidified my expensive relationship with them, right then.
They hooked my up with magazines after Sandy Hook, too. Spent 30 minutes with me on the phone, to gather them up for me. I could go on and on about them, and the stories - they're just great people...
